Does the Oryx use Optimus, or does it require those PopOS applets to switch the GPUs? The output of "System Information" would help.

It turns out we needed to also install virtualgl (plus virtualgl-libs:i386 for 64-bit) to get Bumblebee working on several test laptops, so the Nvidia Installer has been updated to add those.

There's been a request to also port over "nvidia-prime" from Ubuntu, but I think you need to boot with systemd to have that work.

Yes, I believe the Oryx is the only laptop System76 puts out with the Optimus option. The current configuration is using the nouveau graphics driver. I just, as per advice above, installed the NVIDIA drivers via MX Tools. I'll know after a reboot whether that works.

Well, after installing the NVIDIA drivers via MX-tools, I was given a warning by the installer that the NVIDIA proprietary drivers were incompatible with the currently installed Nouveau drivers, but that a reboot would correct the problem. I rebooted, but got a black screen with the following message:

mmc0: Unknown controller version (3). You may experience problems

Indeed. So I reinstalled MX and am now running again on the default Intel graphics.

The updated MX Nvidia installer now installs that by default, since we found that seems to be necessary for Bumblebee now on many/most? machines. The nice thing is that formerly troublesome machines like the MSI GP63 laptop, plus at least one Dell, now have Bumblebee just work out of the box with MX 18 and the new installer.

A further update. I have for the time being given up on Arch based installs with the Oryx. I haven't been successful yet in getting MX to deal with the NVIDIA card, but it does fine with the Intel. I decided to install Mint as a third boot option, and with some juryrigging with "nauveau=modeset:no" or something like that in the boot process (don't remember the exact syntax), I was able to eventually load the NVIDIA drivers and toggle between Intel and the NVIDIA card with Mint. Since MX and Mint, and even Pop_OS share Debian/Ubuntu upstreams, maybe what I did with Mint today would be relevant to MX. Anyway, I can supply the links that helped me with the Mint install if you aren't already familiar with that. Cheers, and happy holidays.
